I am in charge of developing a searchable database which should allow users to search for any key term in every fils content in a folder. Note that I need to search for filescontent, not file name. Right now, users usually have to searchfor every file to look for particular filecontents with any key terms.
View 2 RepliesI am in the process of creating a program, using Visual Basic Express, for a physics professor who has recently had to rename all 1500 questions for his course. I created a database that has the old names, new names, and the entire contents of each question. The program seemed an easy enough idea, but has proved to be very difficult for me. I am new to programming (this is only my third go at it) and have searched for an answer to my problem for at least 20 hours, and have yet to find anything that will work for what I need.
What I would like is to have a text box in which he can type in a keyword (such as "Sun", "ISS", "Force", etc) and for the program to search throughout the entire "questioncontents" column and pull out any questions that contain those words into the datagrid. As of yet the closest I have gotten is for it to search the first word of the column, which is not very useful since most of them start with "The". I had also thought of creating several keyword columns and then just having it search through those, but I couldn't figure out how to apply the filter to multiple columns.
We have users to type in Business Requirement in a text box.For instance : DOB Field is mandatory in Service Request Screen.
I am planning to define all the keywords in my code and once search button is clicked it should look for the keywords and throw a msgbox with number of keywords found.
Any code snippet vb for searching key words like name or id no. On my database connected with my vb form application?

The "keywords" are known in advance - but the number is variable.
The text is large - I've had 50000 byte strings in tests already...

View 5 RepliesI have a question here. I'd like to develop a vb.net program to run thru all source code in a folder to look for certain strings.my initial thought is to create an .ini file then program will read the strings then start searching in the source code for the strings entered.
the final output will be an excel sheet, stating the filename and the line number.
is this a good way to do it? if yes, can i ask for a skeleton program?if no, any other way?

I am trying to write a program that deletes temp files from my entire c drive. windows 7 will not allow any file manipulation. access denied . everything works fine in windows xp. what needs to be changed in my code to allow anyone to install this program on their computer and run it without errors like this. I need to change my code to correct this not windows 7, as other people will be installing this on their systems and they can't be setting their c drives. every answer i've found online is either to change c drive to have no security or set the code to demand uac to run as administrator(which doesn't work )
View 7 RepliesI am using the .getdirectory to scan my whole c drive for certain files to be backup. e.g *.doc. however when i run the code, i hit into error. stating folder access error. one of the folder which cause the error is system information volume.
View 8 RepliesI can search all the images with .jpg extension and pass it to the fancybox gallery , The issue is i just want the images of particular productid for instance if a product has 5 images , and they are saved as (productid_imagenumber.jpg) , therefore a product with productid 99 will be saved as 99_1.jpg , 99_2.jpg similarly 99_5.jpg,I can pass the productID but i cant find a away just to get the images of that productID , instead of getting all the images which is done by the function below:
Dim directory As DirectoryInfo = New System.IO.DirectoryInfo("C:Images")
Dim allImages() = directory.GetFiles("*.jpg", SearchOption.AllDirectories)
Dim strContent As String = ""

I want to create Desktop Search Engine using vb.net. While searching on internet someone suggested that I should use B+Tree indexing for quick results. But I don't know how to implement B+Tree indexing for searching file.
View 7 RepliesI'm creating an app that has check boxes that will define a search. The files all reside in one folder. I've looked at some tutorials that use io.directory.getfiles and I can get this to work. But what I think i want to use is: io.path.getfilename because I don't need the path (though I'm about ready to make an exception).
When should I use io.path.getfilename and can I use that method to do a search? I can't figure that out. I would think it would react as io.directory does but I am incorrect.....
Here is the code. Its short becasue I'm just figuring things out first:

On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
View 1 RepliesI want a form to search a directory (which i specify in the code) and then list all files with a file exstension that is .amxx .And that's not all, it should list them in a checked listbox.And of course a little + is that it only list the name of the file, not the hole directory + filename. But that feuture i don't really need, just for good looking.I looked into the problem and i tried something with DirectorySearcher but with no success.

I need to scan all files on our solution (aspx, js, ascx, etc). Our solution contains 22 projects all in all. What I need to accomplish is to search for all files which contains "img=" in its content (not filename containing "img") I don't want to do this manually of course (opening and checking files one by one). How I can do this faster.

I'm trying to create a folder search operation. The folder will have several text files (.txt), and user will specify the folder path and a search string, and the program will search the exact string within the text files which are located in the specified folder, and show the files. So far I've done nothing. I don't know how I can do folder operations with vb.net. a link to reading material.

I have a file search that I want the user to select the folder they are searching the file in. At the moment I have
If Check.Text = "Correct" Then
If My.Computer.FileSystem.FileExists("C:Systemsfile.txt") Then
1CheckBox.Checked() = True
Else
1CheckBox.Checked = False
End If
However this check will be used for various files and its not usable if the FileExists directory stays the same ie searching the same folder and file for different records. I have a FolderBrowseDialog that I want the user to select the folder first in where to search and then within this chosen folder the static file will be checked. I have this as my folderbrowsedialog:
Dim Browser As New FolderBrowserDialog
Browser.Description = "Please select ."
Browser.ShowNewFolderButton = False
Browser.RootFolder = "c:"
Browser.SelectedPath = "c:windows"
If Browser.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.text.Text = Browser.SelectedPath
End If
I tried adding in this code to the actual file check to encoporated the dynamic folder search but its bringing up errors and not working, I have this:
Dim path As String = "Browser"
Dim f As ReadOnlyCollection(Of String) = My.Computer.FileSystem.GetFiles("test.xlsx")
If My.Computer.FileSystem.FileExists("test.xlsx") Then

I am having a problem. The IO.Directory.GetFiles code is resulting in error do to the fact that it is trying to access the Temp folder in the Windows folder on drive C:. Apparently that folder is restricted... When the code encounters that folder the code stops retrieving files. Is there a way around this? Is there somewhere i can give my program administrator access? If not then am i able to skip the files in that location?
I have an application and in this application there is a search option. I want the seach to search for all music and video files. I keep getting UnauthorizedAccessException error and I'm assuming its because my application is trying to access a file for witch access is being denied. This is the code that I am using.tbsearch is textbox and results is the listbox that the search results get added to.
Dim dirPath As DirectoryInfo = New DirectoryInfo("G:")
For Each file As FileInfo In dirPath.GetFiles
(tbsearch.Text & "*.mp3", SearchOption.AllDirectories)
results.Items.Add(file.FullName)
Next
Also, how can't I make it so that only the name of the file found is added, not the full path. I know that I could instead of using file.FullName use file.Name but then I can play the media file because the application wont know where to find it. Any code that I could use to add only the found file name to the listox? Perhaps I need another hidden listbox that get the full name and then the results listbox retrieves only the last part of the path?
I am trying to develop an application that will let me do the following
1) Be able to search to large binary files for a specific byte array (header) and to continue searching for another byte array (footer). Then i want it to copy the section of the binary file between these 2 locations to a specified file. Then the program is to continue searching for any other header/footers An example would be search a large file and carving out the jpgs it finds etc. This routine would have to be able to handle raw images of 20gb or more if needed.
I need code for the function filesystemobject which gets the text files from a folder when searched for.
View 1 RepliesSo I've been using some code to generate directories and such in a custom treeview, but am looking to expand upon this idea. While it's not using recursive functions, and only calls functions when expanding levels, I'm not quite sure how to put some of these together.find a way to just search through all folders on the PC. If the folder contains audio files, that folder is than added to an array (searching a folder for audio files and adding that folder to an array is done). It's just recursivly searching all folders on the PC.Here is the code I've been using for the treeview (I'm not sure if it can be adapted):
Public Function ListAllDrives() As String()
Dim arDrives() As String
arDrives = Directory.GetLogicalDrives()[code].....
